Question | Answer |
A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds teh atoms together | Chemical bond |
Why are most atoms chemically bonded to each other | Most atoms are less stable existing by themselves than when they are combined. By bonding with each other, atoms decrease in potential energy, thereby creating more stable arrangements of matter. |
Main-group metals tend to lose electrons to form what type of ions | Positive ions or cations. |
Non-metals tend to gain electrons to form what type of ions | Negative ions or anions. |
Chemical bonding that results from the electrical attraction between cations and anions is called | Ionic Bonding |
Results from the sharing of electron pairs between two atoms | Covalent Bonding |
True or False: Bonding between atoms of different elements are rarely purely ionic or purely covalent? | True |
A measure of an atom's ability to attract electrons. | Electronegativity |
The degree to which bonding between atoms of two elements is ionic or covalent can be estimated by doing what | Calculating the difference in the elements' electronegativities |
Bonding between atoms with an electronegativity differenct of 1.7 or less has an ionic character bonding of | 50% or less |
Compounds with 50% or less are classified as | Covalent |
Bonding between two atoms of the same element is | covalent |
A covalent bond in which the bonding electrons are shared equally by the bonded atoms, resultingin a balanced distribution of electrical charge. | Nonpolar-covalent bond |
Bonds having 0% to 5% ionic character, corresponding to electronegativity differences of roughly 0 to 0.3 are generally considered to be what type of bond | non-polar-covalent bond. |
Bonds that have an uneven distribution of charge. | Polar |
A covalent bond in which the bonded atoms have an unequal attraction for teh shared electrons is | Polar-covalent bond |
